3 Claims.

This invention relates to a device for rapidly transferring heat from one fluid to another.

While the invention is more particularly intended for use in mechanical refrigerating systems, yetit is also well adapted for use as a means to raise the temperature of liquids which it is desired to heat.

It is an object of the invention to provide an improved construction'of heat radiating walls and conduit means which are so constructed as to operate more efiiciently for the intended purpose and at the same time are capable of being manufactured and assembled at a relatively low cost. More specifically stated, the invention relates to'an improved'construction and combination of conduits and of heat radiating sheet materials or plates in a coacting relation to said conduits, whereby a multiplicity of streams of fluid are, as it were, closely interwoven with each other, though at all time separated from each other by walls of thin material.

In the heat transferring structure provided by this invention, there are no alcoves or sheltered spaces where either of the two fluids between which the exchange of heat is taking place, can be in a stagnant or static condition, but continuous, eflicient exchange of heat is assured, a steady progressive movement of fluid from intake to outlet across the entire extent of the device is occurring.

In one of its more limited aspects the invention pertains to an improved combination of conduit and heat radiating plate; also to improved supporting or spacing fins carried by spaced plates which form a part of the heat exchanging assembly.

Other objects, advantages and features of the invention will hereinafter appear.

Referring to the accompanying drawing, which illustrates what is at present deemed to be a preferred embodiment of the invention,

Fig. 1 is a vertical section of the device on line l-l of Fig. 2.

Fig. 2 is a transverse section on line 22 of Fig. 1.

Fig. 3 is a cross section on line 3-3 of Fig. 2.

Fig. 4 is an elevational detail of one of the partition plates.

Referring in detail to the drawing, which shows a structure utilizable either as a heater or cooler of liquid or fluid substances, but which, for convenience of description will be described as a cooling device, the casing H is shown having rectangular walls on all sides thereof, viz. the end walls l2, side walls l3, bottom wall or floor I4 and top wall l5. Inan upwardly spaced relation to its floor said casing has a transverse lower cross wall l6 thus providing an intakechamber I1, and in a downwardly spaced relation to the upper wall l5 there is a transverse partition l8 ing boiler type tubes 2| extend through the upper partition l8 and the lower partition [6 and also through all the intervening partition plates 28. These tubes have their end portions peened over at 23 and 24in abutting relations respectively to the partition plates l6 and I8, thus making liquid-tight connections at these points. Also they make liquid-tight fits where they pass through the intervening plates 20.

The spacing apart of the intervening plates 28 is maintained by providing said plates with reversely directed flanges 25 and 26 near each side of the structure as shown in Fig. 1. The flanges 25 are directed downwardly to support the plates of which they form a part, and the flanges 26 are directed upwardly in each instance to support the plate next above. Such of said flanges 25 and 26 as are located adjacent to the casing walls I3 are also located adjacent tothe corner portions of the casing and hence serve as deflectors which deflect portions of the fluid stream passing through the openings beside them into said corner portions, thus insuring against a stasis of fluid in anypart of the casing.

The upper partition plate I8, lower partition plate l6 and the intervening plate 20 are all provided laterally extending annular flanges 30 within which the upstanding tubes 2| tightly fit in the completed assembly. Said flanges 30 not only afford superior fluid-tight fittings but they also furnish additional surface contacts between the plates of which they form a part and said tubes which pass through them. Hence improved heat conduction results between said plates and tubes.

When the device is used for liquid cooling, the refrigerating liquid will be supplied through a liquid supply conduit 35 which enters the lower chamber l1 and is furnished with a plurality of outlet apertures 31 some of which are shown opening laterally and others upwardly, thus affording a substantially uniform distribution of the liquid throughout the chamber [1. After coming out of said apertures the refrigerant passes up through the tubes 30 and not only cools their walls but is rapidly conducted to the.

Assuming that the device is being used to cool water circulating therethrough, the water being cooled enters through the conduit 46, and then, after circulating back and forth over the partition plates and across the tubes 2| which are being supplied with the: refrigerating liquid, passes around said tubes, and leaves the casing through the tube 42 being thereby conveyed to a the place where the cold fluid is being used.

A conventional thermostat 4!! is shown projecting into the central portion of the casing. Said thermostat may control any suitable valvular means to regulate the supply of a refrigerating liquid to the device.

I claim:

1. In a structure of the kind described, a casing having a transverse partition in a downwardly spaced relation to its top wall thus providing an upper chamber therein, said casing,

having a transverse partition in an upwardly spaced relation to its floor, thus providing a lower chamber therein, other'transverse partitions between aforesaid partitions thus providing a series of transversely extending chambers, said partitions having flanges laterally outstruck from opposite edges of alternate partitions, thus forming spacers between said partitions and at the same time providing alternate and laterally staggered end passages immediately adjacent to opposite sides of said casing thus affording a back and forth flow of liquid progressively through said casing, there being inlet and outlet means for said casing.

2. In a structure of the kind described, a heat transferring assembly including an elongated casing which is rectangular in cross section, a series of substantially parallel, spaced apart plates fitted within the cross sectional area of said casing and a plurality of fluid-conducting tubes, each of said tubes projecting through a plurality of said plates, intermediate plates of said series of plates having laterally directed flanges which abut against adjacent plates and act as spacers, certain of said "flanges being adjacent to corner portions of said casing and serving as deflectors to deflect the fluid stream into said corner portions.

3. In a heat exchanger, an elongated casing rectangular in cross section, a series of spaced partition plates spanning the cross-sectional extent of said casing, a series of fluid circulating tubes extending through said series of plates, there being plates of said series which have, adjacent to corners of said casing, deflected edge portions whereby openings are formed immediately adjacent to the wall of said casing and at the same time deflectors are provided which are positioned to direct portions of the fluid stream passing through said openings into said corner portions of the casing.
